M, Y BY Mr A TTORNEYS UNITED STATES To all whom it may concern.- 4 l Be it known that I, OTTO PQBAILER, residing in Memphis, inthe county of Shelby and I State of Tennessee, have made certain new l a and useful Improvements in Eyeglasses, of

i [which the following is a specification. l

. 1 My invention is an improvement in eye- .glasses, and particularly in the devices for connecting the postwith the bow-spring; and the invention has for an object to provide means by which to prevent the screw which connects the post and bow-spring from accidentally becoming loose.

The invention consistsin certain novel constructions and combinations of parts, as will behereinafter described and claimed.

In the drawings, Figure 1 is a face view of a portion of a pair of eyeglasses embodying I my invention. Fig. 2 is a face View showing the head of the fastening-screw and the lockt ing-plate applied thereto and to the flanged end of the post. Fig. 8 is a detail perspective view of the post. Fig. 4 is a detail perspective View of the locking-plate. perspective view of the screw, andFig. 6 is a cross-sectional view on about line 6 6 of Fig.2. I The glass A may be secured to the post B in any suitable manner, the post being provided with the end flanges B, projecting from its opposite sides and forming a recess to receive the head D of the screw D and also I to receive the body portion E of the lockingplate E. The flanges B are slotted at b in line with notches b in the baseplate, from a which said flangesproject. In practice the spring-bow F may be seated in the recess 0 againstthe base-plate of the post and the I screw D be turned through a suitable opening in the springF and into a socket d formed to hold such parts securely together. The head D of the screw is non-circular, being 1 shown as angular, and the plate E of the lock E has an opening e to fit the said head D, a which is applied as shown in Fig. 2 and has I 4 its endarms E bent into the slots b and i notchesband'clenched beneath the base-plate of thepost, as shown at e in Fig. 6. When thus applied, as shown in Figs. 1, 2, and 6, n the locking-plate and the screw-head will be I I seated in the recess of the post, and the arms PATENT Fig. 5 is a detail in the post, and the'screw may be tightened FFICE.

SPECIFICATION forming part of Letters Patent No. 681,092, dated August 20, 1901.

Application filed May 10, 1901. Serial No. 59,585- (No model.)

E of the locking-plate will seat in the slots 6 and notches b and rest flush with the outer surfaces of the flanges B, avoiding all obstructions or projections on the flanged end of the post, as will be understood from Figs. 1, 2, and 6.

I By the described invention the fasteningscrew will be positively locked in turning by means of the 1ocking-plate,which can be readily removed whenever for any reason it is desired to release the screw D.

In the use of the expression non-circular in the foregoing description and appended claims I wish it understood that I mean to distinguish thereby'from a head and an opening to receive the same, which are circular, as in my device the head cannot turn in the opening in the plate, it being manifest that While I have shown the head D as angular in crosssection it might be made of other cross-sectional form than that of the circle, so it could not turn when fitted in a corresponding opening in the plate E.

Having thus described my invention, what I claim, and desire to secure by Letters Pat Bull, is

1. The combination in an eyeglass of the bow-spring, the post having a base-plate and provided at the opposite sides thereof with flanges having slots and also having notches in the base plate in line with said slots, the fastening-screw having a non-circular head and seated between the flanges of the post and the locking-plate having a main portion fittingbetween the flanges of the post and provided with an opening receiving the head of the screw, said locking-plate having the end arms bent within the slots of the flanges and the notches of the base-plate and clenched beneath the said plate substantially as shown and described.

2. The combination in an eyeglass of the post having flanges and a seat for the screw between said flanges, the screw having a noncircular head arranged to lie between the said flanges, and the locking-plate having its main portion lying between the said flanges and provided with an opening to receive said head and arms bent into engagement with the post substantially as set forth.

3. The combination with the post having the slotted flanges and the screw having its e n-ei eular and arranged toliebetween I ection with th p s sebstantiallyas shown said flanges, of the locking-plate having its and described. main portion formed to lie between said flanges and having an opening to receive the head of the screw and provided at the ends Witnesses: of the m p r with arms fitting in the EDWARD L, BURNS, slots of the flanges and bent into locking con- JAMES J.
